Conveyor Belt - Documented Cost Saving

Using NSK Molded-Oil saved € 9,315


A vegetable-processing company was experiencing repeated ball bearing failures on one of its transport systems. NSK was commissioned to investigate the problem. During the investigation it was determined that a large amount of water was entering the bearings and washing out the grease fill. Therefore, NSK suggested the use of sealed, corrosion-resistant Molded-Oil Bearings, thus increasing the bearing life from approximately 2 weeks to over 9 months.
